Hyperspectral Remote Sensing, Field Spectrometry Monitor Environment
Spectroscopic measurements play a crucial role in several environmental applications and serve as one of the predominate techniques for remotely monitoring Earth’s surface. Spectroscopy makes it easier to identify raw materials as well as contaminants to determine the presence of molecular compounds, found in the water, on the ground, or in the air.

Raman Spectral Cytology Helps Diagnose Thyroid Cancer
If Raman spectroscopy can identify individual cells from various types of thyroid nodules based on unique differences in their spectra, Raman scattering could potentially be a new modality in cytopathology to improve thyroid cancer diagnosis. Researchers at the University of California, Davis set out to measure the effectiveness of this technique by performing a study using thyroid nodules with known diagnoses. These nodules were dissociated into single cells and prepared for single-cell Raman spectroscopy measurements.

Portable Concussion Detector Uses Infrared Light to Measure Brain Metabolism
A new approach to detecting concussion utilizes a laser to deliver infrared (IR) light pulses to the brain, where the light interacts with cytochrome C oxidase (CCO), a mitochondrial enzyme important to brain metabolism. CCO is known to decrease when cells are in distress. Measuring CCO “can tell us if the tissue is healthy and is metabolizing or ‘eating’ properly,” Ioulia Kovelman, associate professor at the University of Michigan, said.

Guoan Zheng, a University of Connecticut (UConn) professor of biomedical engineering, has published his findings on a successful demonstration of a lensless on-chip microscopy platform in Lab on a Chip. Zheng suggests his platform eliminates several of the most common problems with conventional optical microscopy while providing a low-cost option for the diagnosis of disease.

A tumor-highlighting technology called OTL38 enhances the visualization of lung cancer tissue through near-infrared imaging, providing surgeons with a significantly better chance of finding and removing more cancer than previously possible. The results of a phase 2 clinical trial for OTL38 were presented at the 56th Annual Meeting of The Society of Thoracic Surgeons, Jan. 25-28, 2020, in New Orleans. Six institutions participated in the trial — the University of Pittsburgh, the University of Pennsylvania, Harvard University, Cleveland Clinic, Leiden University, and the University of Texas MD Anderson Cancer Center.

Raman Spectroscopy: Theory, Practice, and Applications
Wed, May 6, 2020 1:00 PM - 2:00 PM EDT
This webinar, presented by Hamamatsu Corp., will review the basic theory behind normal, resonant, and surface-enhanced Raman scattering. It will discuss the hardware required in a working Raman spectrometer; describe data analysis and presentation; and give examples of common applications. In addition, it will examine some of the market challenges and solutions. You will learn about the basic setup of a Raman spectrometer, performance trade-offs associated with hardware limitations, and the factors that influence the choice of the illumination laser.
